fastboot tool is a convenient way to flash the eMMC, so
add support for it.
Examples of usages:
On the mx6sabresd:
=> fastboot 0
On the Linux PC connected via USB:
$ sudo fastboot getvar bootloader-version -i 0x0525
bootloader-version: U-Boot 2018.01-00550-g7517cfe
finished. total time: 0.000s
Shawn Guo described the following method for flashing the eMMC
via flashboot:
"I booted the board into Debian via NFS, and then use gpart to create GPT
partitions on the eMMC. With CONFIG_EFI_PARTITION enabled in U-Boot, I
can list the partitions on eMMC as below.
=> mmc dev 2
switch to partitions #0, OK
mmc2(part 0) is current device
=> mmc part
Partition Map for MMC device 2 -- Partition Type: EFI
Part Start LBA End LBA Name

=> fastboot 0
At this point, I can do 'fastboot flash system system.img -i 0x0525' from
host PC."
